What Really Is a Tub to Shower Conversion?
A tub to shower conversion is a structural upgrade service in which an existing bathtub — along with its enclosure and hardware — is taken out and replaced with a purpose-built shower unit. The scale of the project is shaped by your existing bathroom plumbing configuration, your style choices, and whether you need to expand the shower's footprint beyond the original tub's position.
On a technical level, the process involves capping the existing tub drain and supply lines, taking out the tub itself and any tile, drywall, or backer board that was tied to it, then constructing the new shower pan with a code-compliant slope toward the shower drain. New moisture barrier is applied before any surface covering goes on. Plumbing is rerouted to serve the new showerhead height and any extra spray features you add.
The finished product is a fully waterproofed shower that drains correctly for the long term. A tub to shower conversion done by experienced hands is not just a surface-level change — it is a complete transformation to your bathroom's plumbing, waterproofing, and layout.

The Tub to Shower Conversion Procedure Step by Step
- Project Assessment and Design — A project consultant visits your home to measure your existing space and infrastructure. We review your goals, design preferences, and budget so the proposal reflects exactly what you want.
- Demolition and Removal — The existing bathtub, tub surround, and any damaged or outdated backer board are demolished and cleared. Any plumbing connections tied to the old tub are professionally handled to make room for the updated fixture configuration.
- Framing, Waterproofing, and Substrate Work — This is arguably the most technically demanding stage of a tub to shower conversion. New moisture-resistant substrate is fastened to the structural framing, and a industry-standard moisture barrier is applied across every area that will contact water. The floor base is sloped correctly to avoid standing water.
- Plumbing Rough-In and Fixture Placement — Skilled tradespeople on our crew install the new shower valve, drain body, and supply lines according to your chosen layout. Whether you went with a standard showerhead or an upgraded fixture package, everything is roughed in at this stage.
- Tile, Stone, or Panel Installation — Tile setters apply your preferred wall and floor covering using appropriate mortar, grout, and setting materials. Every tile edge is grouted and inspected before glass or curtain hardware is installed.
- Hanging Doors, Glass, or Hardware — Depending on your preference, we hang your chosen enclosure system. Each component is set into the tile or framing to prevent loosening over time.
- Quality Check and Project Sign-Off — Once the full shower is finished and installed, we perform a careful quality review. Every seam at the base and wall corners are caulked with professional-grade caulk. We show you the completed project and confirm everything is exactly what you wanted.
